FASTENERF OR THE MEETING-RAILS OF SA SHES.

SPECIFICATION forming part of Letters Patent No. 495,905, dated April18, 1893.

Application filed SeptemberE, 1892. Serial No.'445,114=. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHRIST NEUMANN, of the city of St. Louis and Stateof Missouri, have invented certain new and useful Improvements inAutomatic Sash-Fasteners, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates to improvements in sash-fasteners, and consists inthe novel arrangement and combination of parts as will be more fullyhereinafter described and designated in the claims.

The class of fasteners hereinafter described are especially designed forattachment to the meeting rails of the sashes, which are of the usualconstruction and design and the fasteners may be applied thereto withoutin any way disfiguring or cutting the wood.

The obj ect. of myinvention is to provide an improved lock which willfasten automatically when the lower sash is pulled down or closed andwhich is adapted to be unlocked by hand in the usual manner.

From the descriptions it will be seen that the objections heretoforemade to sash-fasteners are overcome, and the necessity of locking thesashes by hand, is dispensed with asmy device is entirely automatic inits operation.

In the drawings: Figure 1 is a sideview of my complete invention appliedto the meeting rails of ordinary sashes and shows the same in a positionwhen locked. Fig. 2 is a top plan View of the two members of my device,applied as above stated, and showing them interlocked. Fig. 3 is aperspective view of the member which is secured to the upper sash. Fig.4 is a side elevation of the member which is secured to the lower sashand showing the side adjacent the upper member. Fig. 5 is a top planview of the two members when unlocked. Fig.6 is an end verticalsectional view, showing the member upon the lower sash in readiness toengage the member upon the upper sash, and showing the rails in section.Fig. 7 shows detail views of the locking lever ready for engagement, andwith the other parts of the two members removed. Fig. 8 is a perspectiveview of the ,weighted arm, rocking shaft, interlocking le-- ver andlocking arm, said parts comprising portions of the member secured to thelower sash. Fig. 9 is a sectional view taken on a line 00a: in Fig. 5.Fig. 10 is a perspective view of the locking block made use of incarrying out my invention. Fig. 11 is a sectional view on a line y y inFig. 5. Fig. 12 is a top plan View of a modification carried out in theconstruction of the member applied to the lower sash and showing thesame in a position when unlocked. Fig. 13 is a View similar to Fig. 12'except in that it shows the construction when locked. Fig. 14: is a sideelevation of this construction with the locking block removed. Fig. 15is a view in perspective of the locking arm and showing the Weightedlever attached thereto.

Referring to the drawings: 1 indicates the meeting rail of the lowersash 2 made use of in window construction, and which is of the usualdesign.

3 indicates the meeting-rail of an ordinary upper sash 4. As is wellknown, the lower sash 2 is adapted to slide upwardly in a plane adjacentthe upper sash 4 and when thelower sash 2 is down or closed, the uppersurfaces of both the meeting-rails 1 and 3 are in horizontal alignment.

I will first proceed to describe the construction of the men1ber5 whichis the one secured to the meeting-rail 1 of the lower sash 2. consistsof a base-plate 6 substantially rectangularin form, and having suitableperforations 7 through which screws are placed to secure it to themeeting-rail 1. The edge of the plate 6 adjacent to the meeting-rail 3has a portion 8 cut away in order to allow the operation of certainparts hereinafter named.

For the sake of conciseness, I will refer to the side of theconstruction adjacent the meeting-rail 3 as the inner side and the otherside from which the parts are operated by hand, as the outside. Near theouter side of the plate 6 is a rectangular shaped opening 9 which isprovided for the operation of parts therein. At one end of this opening9, and near the left-hand end of the plate 6 is an upright rectangularshaped construction 10 which has a vertical longitudinal opening 11 inthe same, said opening being oblong in form and designed for theoperation of parts therein. Said casing 10 extends upwardly at rightangles withthe base plate 6 and in one side, the same being the sidetoward the opening 9, has a rectangular shaped opening 12 for purposeshereinafter set forth. Mounted in the inner side of said opening 9 andprojecting upwardly from the inner edge thereof, is a bearing-block 13one end of which adjoins the casing 10.

Immediately adjacent the inner edge of the cut-out portion 8 andextending upwardly therein at right angles with the plate 6, is abearing block 14 similarin construction to the block 13, in that theyare both provided with circularapertures 15in which the rocking shaft 16is mounted and has its bearing. Upon the outer end of said rocking shaft16 is keyed an eccentrically mounted locking arm 17 the extending end 18of which projects inwardly through the opening 12 in the casing 10 andis adapted foroperation ashereinafter described. Upon the inner end ofsaid shaft 16 is keyed a locking lever 19 and intermediate of said lever19 and the arm 17 and secured to the shaft 16 is a small shaft 20extending at right angles therefrom and having its free end 21 weightedto facilitate certain operations. A collar 22 preferablya part of thelever 19 projects from the inner face of said lever 19 toward the shaft20 and serves as a gage for a horizontal movement which the shaft 16 andparts connected therewith assume in operation. The lever 19 is providedwith an extending arm 23 in the same plane as its surface, and having acurvilinear slot or opening 24 immediately below and separating it froma tooth shaped projection 25, the operation of which will be hereinafterdescribed. The locking block 26 operative in the vertical opening 11 inthe casing 10 consists of a rectangularshaped block adapted to fitsnugly in said opening 11 and having a handle 27 for hand operation inan elongated slot 28 in the outer wall of the casing 10. The shaft 16 isprovided with a spiral groove 29 which starts at the shaft 20 and rangesup onto the top of the shaft and stops at the collar 22. The bearingblock 14 is provided with a feather 30 which extends downwardly intosaid slot 29 thus causing the sides of said slot 29 to act as a cam inthe operation of the lever 19.

Having described the parts of one member I will now set forth theconstruction of the member which is secured to the upper sash. It has abase plate 31 having apertures 32 through which screws are placed tosecure the same to the meeting-rail 3. Upon its outer side and extendingupwardly at right angles from the base plate 31 isa lug 33 whichapproximately occupies about half the width of the plate 31 and has uponits inner side a projection 34 which serves as a collar to prevent therubbing against its inner surface of a locking-dog 35 which is pivotallymounted to the side thereof. The locking-dog 35 is eccentrically mountedand has its upper face 36 canted toward the lug 33 and provided with atransverse projection 37 which is of the shape of an inverted U incross-section and which in operation is adapted to engage in a similarshaped transverse opening 38 in the under sideof the projecting arm 23upon the lever 19. Adjacent its upper edge and upon the side of the dog35 which is next to the lever 19 when the device is locked is aprojecting ing 39 which is adapted to be engaged by the lever 19 in itsdescent to effect theinterlocking of said lever and the dog 35. Thenormal position of the dog 35 is with its elongated end 40 resting onthe base-plate 31 and its opposite end 41 above the plane of itsmounting and said end 41 is the same form in outline as the slot 24 inthe lever 19 and 3 when the two members are locked together these twoparts are interlocked.

Having fully described the construction of the parts of my invention,Iwill now proceed with its operation. To facilitate a clearer and betterunderstanding of the descriptions, reference should be had to theillustration wherein Fig. 1 shows the two members locked together, Fig.6 shows them in the act of being locked, and Fig. 5 shows the positionof the parts as shown in Fig. 6 when looking down upon them from above.Mention has heretofore been made of the peculiar horizontal movementattained by the rockingshaft 16 and its parts connected therewith, bythe use of the feather 30 engaging the slot 29 and which causes theshaft 16 to have this peculiar side motion when the shaft is turned. Thenormal position of the weighted end 21 of the shaft 20 is with saidweight 21 upon the base plate 6 and therefore the under side of the arm23 is in a horizontal plane, and in readiness for the engagement of theend 41 of the dog 35 when the lower sash 2 is brought lower down. Whenthis engagement of the dog 35 in the slot commences, the lever is tiltedup and consequently the shaft 16 is turned, the weight 21 lifted, andthe end 18 of the arm 17 lowered and the farther down the sash ispulled, the more movement is implied to each of the above named parts,and

by reason of the feather 30 operating in the spiral groove 29, the shaft16 and its parts move outwardly toward the other member. As the end 18of the arm 17 goes down, the locking block 26 follows its movement untilsaid arm 17 has assumed a position wherein the end is far enough fromthe outer wall of the casing 10 to allow the block 26 to fit in betweensaid end and the wall of the casing,

thus permanently looking all of the parts, with the end 41 of the dog 35fitting into the curvilinear opening 24 in the lever 19. When completelylocked the parts have assumed a position as shown in Fig. lwith theweight 21 elevated from 0% the base-plate 6 and the locking block 26wedged between the end 18 of the arm 17 and the opposite inner wall ofthe casing 10. Therefore, in order to release the engagement of theparts and to unlock the members in order that the lower sash can beraised, it is necessary to lift the block 26 by pulling up on the handle27. When the lower sash is pushed up the parts still retain theirposition as when locked until the dog is entirely free from itsengagement in the slot 24, when said weight 21 gravitates toward theplate 6 and all of the parts are ready for a repetition of theoperation.

It is impossible for the parts to become unlocked when locked, except bythe hand operation just described and no amount of tampering can causethe parts to disengage as the downward movement of the locking block 26is stopped by the upper surface of the meeting-rail 1 and can only belifted in the above described manner. Therefore, it is proper that Iterm my improved sash-fastener burglar-proof, as in manufacture it'isintended that it be constructed of some malleable metal which willpreclude any danger of cracking or breaking by the jarring or forcing ofthe windows.

To bring about the horizontal as well as rocking movement of the shaft16 and its parts, I could construct the shaft with a spiral feather uponits periphery to operate in a slot in the bearing block 14 in place ofthe construction which I have shown.

It will be noticed that the construction of the lever 19 and the dog 35is such that they are made substantially self-balancing in order tofacilitate the ready and quick operation of the parts.

In Figs. 12, 13, 14, and 15 I have shown a I modification by means ofwhich I arrive at the same results with a simplified construction andwhich practically includes the same parts.

To replace the bearing blocks 13 and 14 I make use of a bearing-block 42which is wide enough to provide a balancing bearing for the shaftmounted therein which has a groove 43 running spirally in the surface ofits periphery and which is engaged by a feather 44 which projects fromthe block 42 into said slot 43.

Instead of having a separate weighted arm such as 21, I have provided aweighted arm 45 which has a connection with a locking arm 46. Upon theopposite end of the shaft is mounted a locking lever similar to thelever 19 and which has the same function in operation. It will be seenthat this arrangement of the parts brings about the same results with amuch narrower construction of base and a simplified form of constructionand the operation of which in looking, is similar to the formerconstruction.

It will be seen from the description of this modified form ofconstruction, that the article can be manufactured at a greatly reducedcost and will present a very neat appearance upon the meeting-rail ofthe sash.

The member of this fastener which is secured to the meeting-rail of theupper sash is not modified in any way as I believe it to be as simpleand certain in operation as would be possible.

Having fully described my invention, what I claim is 1. As animprovement in sash fasteners, a locking device consisting of. arocking-shaft having a spiral horizontal movement, a vertical, slottedcasin g adjacent to said shaft, a lever project-ing from the latter andinto the casing, and a block corresponding to and working in the casingand adapted to bear upon the end of said lever, said bloek beingprovided with a projecting operating knob or handle; substantially asand for the purpose set forth.
